Title: Procede pour l'obtention de dioxyde de manganese
Inventor: WANG ENOCH I
IPC: C25B11/04
Filed: 1993-08-04
Abstract: L'invention se rapporte à la fabrication, par procédé chimique, de bioxyde de manganèse. Le produit de bioxyde de manganèse obtenu se présente sous la forme de particules caractérisées par des protubérances analogues à des filaments, faisant saillie hors de sa surface. Les particules de bioxyde de manganèse présentant de telles caractéristiques de surface peuvent être fabriquées par la mise en réaction de sulfate de manganèse avec du peroxodisulfate de sodium dans une solution aqueuse. Le procédé peut être régulé de façon à produire du bioxyde de manganèse de forte densité. Le bioxyde de manganèse obtenu selon ce procédé peut être directement déposé sur la surface de particules de bioxyde de manganèse électrolytique (EMD). Ce produit peut particulièrement être utilisé comme matériau de cathode actif dans des piles électrochimiques.

Patent CA-2146470-A1 (CA)
Title: Fire hose container
Inventor: GONSALVES GAIRY J
IPC: B65D25/38
Filed: 1995-04-06
Abstract: A container for storing, transporting and unloading fire hose in situations where there is a need to lay multiple lengths of hose. Such is often the case with a forest fire. The container has top bottom, front, back, and side panels which can be closed and which, when the front panel is fully opened, form a trough into which the fire hose can be accordion folded. The front panel has two overlapping doors which can be opened, while the rest of front panel, comprising two outer doors, remains shut. This creates a vertical slot through which the fire hose can be unloaded. *Velcro fasteners provide a reusable closure means for the front panel. The long edges of the outer doors abutting the center doors have a batten making rigid such edges. The top, bottom, side, front and back panels have a foam insert to prevent deformity and, in the case of the back panel, to cushion the carrier's back. The container is carried on one's back by means of two adjustable, quick release, contoured and cushioned shoulder straps that attach to the top and back panels. Fire hose can be conveniently loaded directly into the container and unloaded with minimal pull out resistance. The container is comfortable to carry and does not bounce or sway.

Title: Method and apparatus for autokey rotor encryption
Inventor: REEDS JAMES ALEXANDER III
IPC: H04L9/16
Filed: 1996-08-09
Abstract: A method an apparatus for block or stream encrypting text uses an autokeyed rotational state vector to encrypt plain text to yield cipher text.  The text is stored as a block in a buffer of an arbitrary number of bytes.  Each byte of plain text in the buffer encrypted to yield a byte of cipher text by using a rotational state vector, and the rotational state vector is updated or changed as a function of one or more of: the cipher text, the plain text and a key.  The encryption operation is advantageously a series of alternating non-linear and linear transformations.  The method of encryption is advantageously involutory in that the encryption method and apparatus for a given key is identical to the decryption method and apparatus with the same key.
